[Pages:6]Understanding Stress: Signs, Symptoms, Causes, and Effects

We all face different challenges and obstacles, and sometimes the pressure is hard to handle. When we feel overwhelmed or unsure how to meet the demands placed on us, we experience stress. In small doses, stress can be a good thing. It can give you the push you need, motivating you to do your best and to stay focused and alert. Stress is what keeps you on your toes during a presentation at work or drives you to study for your exam when you'd rather be watching TV. But when the going gets too tough and life's demands exceed your ability to cope, stress becomes a threat to both your physical and emotional well-being.

What is Stress?

Stress is a psychological and physiological response to events that upset our personal balance in some way. When faced with a threat, whether to our physical safety or emotional equilibrium, the body's defenses kick into high gear in a rapid, automatic process known as the "fight-orflight" response. We all know what this stress response feels like, heart pounding in the chest, muscles tensing up, breath coming faster, and every sense on red alert.

The Body's Stress Response

The "fight-or-flight" stress response involves a cascade of biological changes that prepare us for emergency action. When danger is sensed, a small part of the brain called the hypothalamus sets off a chemical alarm. Stress hormone races through the bloodstream, readying us to either flee the scene or battle it out.

Heart rate and blood flow to the large muscles increase so we can run faster and fight harder. Blood vessels under the skin constrict to prevent blood loss in case of injury, pupils dilate so we can see better, and our blood sugar ramps up, giving us an energy boost and speeding up reaction time. At the same time, body processes not essential to immediate survival are suppressed. The digestive and reproductive systems slow down, growth hormones are switched off, and the immune response is inhibited.

The biological stress response is meant to protect and support us. It's what helped our ancestors survive the life-or-death situations they commonly faced. But in the modern world, most of the stress we feel is in response to psychological rather than physical threats. Whether we're stressed over a looming deadline, an argument with a friend, or a mountain of bills, the warning bells ring. And just like a caveman confronting a sabretooth tiger, we go into automatic overdrive.

If you have a lot of responsibilities and worries, you may be running on stress a good portion of the time--launching into emergency mode with every traffic jam, phone call from the in-laws, or segment of the evening news. But the problem with the stress response is that the more it's activated, the harder it is to shut off. Instead of leveling off once the crisis has passed, your stress hormones, heart rate, and blood pressure remain elevated.

Furthermore, extended or repeated activation of the stress response takes a heavy toll on the body. Prolonged exposure to stress increases your risk of everything from heart disease, obesity, and infection to anxiety, depression, and memory problems. Because of the widespread damage it can cause, it's essential to learn how to deal with stress in a more positive way and reduce its impact on your daily life.

Signs and Symptoms of Stress

To get a handle on stress, you first need to learn how to recognize it in yourself. Stress affects the mind, body, and behavior in many ways-- all directly tied to the physiological changes of the fight-or-flight response. The specific signs and symptoms of stress vary widely from person to person. Some people primarily experience physical symptoms, such as low back pain, stomach problems, and skin outbreaks. In others, the stress pattern centers on emotional symptoms, such as crying or hypersensitivity. For still others, changes in the way they think or behave predominates.

The following table lists some of the common warning signs and symptoms of stress. Use it to identify the symptoms you typically experience when you're under stress. If you know your red flags, you can take early steps to deal with the stressful situation before it--or your emotions-- spiral out of control.

Causes of Stress

Top Ten Stressful Life Events

1. Spouse's death 2. Divorce 3. Marriage separation 4. Jail term 5. Death of a close relative 6. Injury or illness 7. Marriage 8. Fired from job 9. Money concerns 10. Retirement

The potential causes of stress are numerous and highly individual. What you consider stressful depends on many factors, including your personality, general outlook on life, problem-solving abilities, and social support system. Something that's stressful to you may not faze someone else, or they may even enjoy it. The pressures and demands that cause stress are known as stressors. We usually think of stressors as being negative, such as an exhausting work schedule or a rocky relationship. However, anything that forces us to adjust can be a stressor. This includes positive events such as getting married or receiving a promotion. Regardless of whether an event is good or bad, if the adjustment it requires strains our coping skills and adaptive resources, the end result is stress.

Major Life Changes

Major life events are stressors. Whether it be a divorce, a child leaving home, a planned pregnancy, a move to a new town, a career change, graduating from college, or a diagnosis of cancer, the faster or more dramatic the change, the greater the strain. Furthermore, the more major life changes you're dealing with at any one time, the more stress you'll feel.

Daily Hassles and Demands

While major life changes are stressful, they are also relative rarities. After all, it's not every day that you file for divorce or have a baby. However, you may battle traffic, argue with your family members, or worry about your finances on a daily basis. Because these small upsets occur so regularly, they end up affecting us the most. Daily causes of stress include:

? Environmental stressors ? Your physical surroundings can set off the stress response. Examples of environmental stressors include an unsafe neighborhood, pollution, noise (sirens keeping you up at night, a barking dog next door), and uncomfortable living conditions. For people living in crime-ridden areas or war-torn regions, the stress may be unrelenting.

? Family and relationship stressors ? Problems with friends, romantic partners, and family members are common daily stressors. Marital disagreements, dysfunctional relationships, rebellious teens, or caring for a chronically-ill family member or a child with special needs can all send stress levels skyrocketing.

? Work stressors ? In our career-driven society, work can be an ever-present source of stress. Work stress is caused by things such as job dissatisfaction, an exhausting workload, insufficient pay, office politics, and conflicts with your boss or co-workers.

? Social stressors ? Your social situation can cause stress. For example, poverty, financial pressures, racial and sexual discrimination or harassment, unemployment, isolation, and a lack of social support all take a toll on daily quality of life.

Internal Causes of Stress

Not all stress is caused by external pressures and demands. Your stress can also be selfgenerated. Internal causes of stress include:

? Uncertainty or worries ? Pessimistic attitude ? Self-criticism ? Unrealistic expectations or

beliefs

? Perfectionism ? Low self-esteem ? Excessive or unexpressed anger ? Lack of assertiveness

Risk Factors for Stress

The presence of a stressor doesn't automatically result in disabling stress symptoms. The degree to which any stressful situation or event impacts your daily functioning depends partly on the nature of the stressor itself and partly on your own personal and external resources.

Stress: How vulnerable are you?

The nature of the stressor

Stressors that involve central aspects of your life (your

marriage, your job) or are chronic issues (a physical

handicap, living from paycheck to paycheck) are more

likely to cause severe distress.

A crisis experience

Sudden, intense crisis situations (being raped, robbed

at gunpoint, or attacked by a dog) are understandably

overwhelming. Without immediate intervention and

treatment, debilitating stress symptoms are common.

Multiple stressors or life

Stressors are cumulative, so the more life changes or

changes

daily hassles you're dealing with at any one time, the

more intense the symptoms of stress.

Your perception of the stressor The same stressor can have very different effects on

different people. For example, public speaking

stresses many out, but others thrive on it. Additionally,

if you're able to see some benefit to the situation--the

silver lining or a hard lesson learned--the stressor is

easier to swallow.

Your knowledge and preparation

Your stress tolerance

Your support network

The more you know about a stressful situation, including how long it will last and what to expect, the better able you'll be to face it. For example, if you go into surgery with a realistic picture of what to expect post-op, a painful recovery will be less traumatic than if you were expecting to bounce back immediately. Some people roll with the punches, while others crumble at the slightest obstacle or frustration. The more confidence you have in yourself and your ability to persevere, the better able you'll be to take a stressful situation in stride. A strong network of supportive friends and family members is an enormous buffer against life's stressors. But the more lonely or isolated you are, the higher your risk of stress.

Effects of Chronic Stress

Chronic stress wears you down day after day and year after year, with no visible escape. Under sustained or severe stress, even the most well-adjusted person loses the ability to adapt. When stress overwhelms our coping resources, our bodies and minds suffer.

Health Effects

Recent research suggests that anywhere from 60 to 90 percent of illness is stress-related. The physical wear and tear of stress includes damage to the cardiovascular system and immune system suppression. Stress compromises your ability to fight off disease and infection, throws your digestive system off balance, and makes it difficult to conceive a baby, and can even stunt growth in children.

Stress and Your Health

Many medical conditions are caused or exacerbated by stress, including:

? Chronic pain

? Heart disease ? Infertility

? Migraines

? Diabetes

? Autoimmune diseases

? Ulcers

? Asthma

? Irritable bowel syndrome

? Heartburn

? PMS

? Skin problems

? High blood pressure

? Obesity

Emotional Effects

Chronic stress grinds away at your mental health, causing emotional damage in addition to physical ailments. Long-term stress can even rewire the brain, leaving you more vulnerable to everyday pressures and less able to cope. Over time, stress can lead to mental health problems such as:

? anxiety ? depression ? eating disorders, and ? substance abuse.

Severe Stress and Trauma

Severe stress reactions can result from sudden, catastrophic events or traumatic experiences such as a natural disaster, sexual assault, life-threatening accident, or participation in combat. After the initial shock and emotional fallout, many trauma victims gradually begin to recover from its effects. But for some people, the stress symptoms don't go away, the body doesn't regain its equilibrium, and life doesn't return to normal. This severe and persisting reaction to trauma is known as post-traumatic stress disorder (PTSD).

Common symptoms of PTSD include:

? Flashbacks, intrusive thoughts, or nightmares about the trauma ? Avoidance of places and things associated with the trauma ? Hypervigilance for signs of danger ? Chronic irritability and tension ? Depression.

PTSD is a serious disorder that requires professional intervention.
